Hi,
you can write to cView like this:

CPP / C++ / C Code:

void CYourSDIView::OnPaint() 
{
CPaintDC dc(this); // device context for painting

// TODO: Add your message handler code here
CClientDC pDC(this);
OnPrepareDC(&pDC); // Get origin adjusted
TextOut(pDC.GetSafeHdc(),1, 2, "HELLO", 5);// and output text
}

well, when creating the SDI, there should be 3 class, the app,mainframe and the viewclass, by default, the view class name would be ="yourProjectName"+"View"

so thats the class that could be used to write to the view with the codes i gave above.

i have seen the sample code u send to me but as i am trying to add a similar code to my own i get an error saying that the OnPaint has been declared in my view class. eventually i intend to display the information say after clicking a certain button. will be here all night. this thing has 2 work 2day! help

I don't see whats your problem, did you declared OnPaint correctly?? Use class wizard to add the 'onpaint' hanler to your view class and try to put the code there.

In case you don't know how to add it:
"In class wizard, choose MessageMaps tabs and choose your view class from the class name and find 'WM_PAINT' from the Message list and add"

Here is how OnPaint would be declared in the headear file:

CPP / C++ / C Code:

// Generated message map functions
protected:
	//{{AFX_MSG(CNewSDIView)
	afx_msg void OnPaint();
	//}}AFX_MSG

this is in your view.cpp

CPP / C++ / C Code:

BEGIN_MESSAGE_MAP(CNewSDIView, CView)
	//{{AFX_MSG_MAP(CNewSDIView)
	ON_WM_PAINT()
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

I think I had given the code and even a sample program, you should put more effort to find how to use it...
